How to re-use pre process jenkins/groovy in each test - shell

Question

Im using the following code to run our voter , currently I’ve one target which is called Run Tests
Which use exactly the same steps as the last (lint) , currently I duplicate it which I think is not a good solution ,
Is there is nice way to avoid this duplication and done it only once as per-requisite process ?
I need all the steps until the cd to the project
The only difference is one target I run
go test ...
and the second
go lint
All steps before are equal
#!/usr/bin/env groovy
try {
parallel(
'Run Tests': {
node {
//————————Here we start
checkout scm
def dockerImage = 'docker.company:50001/crt/deg:0.1.3-09’
setupPipelineEnvironment script: this,
measureDuration(script: this, measurementName: 'build') {
executeDocker(dockerImage: dockerImage, dockerWorkspace: '/go/src') {
sh """
mkdir -p /go/src/github.com/ftr/myGoProj
cp -R $WORKSPACE/* /go/src/github.com/ftr/MyGoProj
cd /go/src/github.com/ftr/MyGoProj
//————————Here we finish and TEST
go test -v ./...
"""
}
}
}
},
‘Lint’: {
node {
//————————Here we start
checkout scm
def dockerImage = 'docker.company:50001/crt/deg:0.1.3-09’
setupPipelineEnvironment script: this,
measureDuration(script: this, measurementName: 'build') {
executeDocker(dockerImage: dockerImage, dockerWorkspace: '/go/src') {
sh """
mkdir -p /go/src/github.com/ftr/myGoProj
cp -R $WORKSPACE/* /go/src/github.com/ftr/MyGoProj
cd /go/src/github.com/ftr/MyGoProj
//————————Here we finish and LINT
go lint
"""
}
}
)
}
}
}

You can use function and pass Go arguments:
try {
parallel(
'Run Tests': {
node {
checkout scm
runTestsInDocker('test -v ./...')
}
},
'Lint': {
node {
checkout scm
runTestsInDocker('lint')
}
}
)
}
def runTestsInDocker(goArgs) {
def dockerImage = 'docker.company:50001/crt/deg:0.1.3-09'
setupPipelineEnvironment script: this,
measureDuration(script: this, measurementName: 'build') {
executeDocker(dockerImage: dockerImage, dockerWorkspace: '/go/src') {
sh """
mkdir -p /go/src/github.com/ftr/myGoProj
cp -R $WORKSPACE/* /go/src/github.com/ftr/MyGoProj
cd /go/src/github.com/ftr/MyGoProj
go ${goArgs}
"""
}
}
}
Update
If some actions can be separated out of runTestsInDocker they probably should be.
For example setupPipelineEnvironment step. I don't know exact logic but maybe it can be run once before running test.
node {
stage('setup') {
setupPipelineEnvironment script: this
}
stage ('Tests') {
parallel(
'Run Tests': {
node {
checkout scm
runTestsInDocker('test -v ./...')
}
},
'Lint': {
node {
checkout scm
runTestsInDocker('lint')
}
}
)
}
}
def runTestsInDocker(goArgs) {
def dockerImage = 'docker.company:50001/crt/deg:0.1.3-09'
measureDuration(script: this, measurementName: 'build') {
executeDocker(dockerImage: dockerImage, dockerWorkspace: '/go/src') {
sh """
mkdir -p /go/src/github.com/ftr/myGoProj
cp -R $WORKSPACE/* /go/src/github.com/ftr/MyGoProj
cd /go/src/github.com/ftr/MyGoProj
go ${goArgs}
"""
}
}
}
Note
If you are running parallel on remote agents you must remember that setup performed on master may be not aviailable on remote slave.
